If the photo frame is slightly larger than the photo, making the picture more open and not fixed, you can use a small trick to fix:

Method: Put one or a few Chipi in the back of the picture and press the glass plate. The horizontal pendulum pendulum is up to the right.

Principle: Using a rubber band to increase the friction between the photo and the glass, this method can also use a fixed large painting.
